Back Red in production of larger hit (4,5)
I believe the answer is:
rear light
'back red' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'production of larger hit' is the wordplay.
'production of' is an anagram indicator.
'larger'+'hit'='largerhit'
'largerhit' with letters rearranged gives 'REAR-LIGHT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for rear light that I've seen before include "car component" , "estate needs one" , "Stern glower" , "safety device!" , "late display of driving" .)
